What are dual adhesive tapes plus double perforation lines on an eco-friendly mailing bag?

On regular courier bags, there is only single adhesive tape like below picture:



But for eco friendly purpose and better user experience, we have below new designs-dual adhesive tapes plus double perforation lines.



What’s the function of dual adhesive tapes?

Suppose one client buys something from your online shop, then you will need to send the required item to him using the first adhesive tape to seal the shipping envelope. After the client receives the parcel, if he is not satisfied with the item, he will need to return the parcel back to you. In this case, if the poly mailer we use is regular single adhesive tape one, the client will need to use a new one to send the parcel out but, since we have dual adhesive tapes for our courier bag, he can still use the same courier flyer to send the parcel back to you.

What is the function of double perforation lines then? OK, if the client wants to use the second adhesive tape, he will need to remove the 1st tape. But glue used for poly mailer is permanent glue. Once sealed, if you want to open it, the whole bag will be destroyed. So to reuse this same mailing satchel, we have the double perforation lines to easily open the bag without tearing the whole bag off.

Thus, dual adhesive tapes plus double perforation lines are two sustainable designs on courier satchels for reusing the satchel.
